A display device includes a display module; a support plate; the support plate including support bars; an opening defined between the support bars adjacent to each other; and a first support portion and a second support portion spaced apart from each other, the support bars being disposed between the first support portion and the second support portion; a support film disposed between the display module and the support plate; and a foam layer disposed on at least one of a first upper surface and a first lower surface of the support film, the foam layer including a core layer having a first modulus and a first thickness; and a skin layer disposed on at least one of a second upper surface and a second lower surface of the core layer, having a second modulus greater than the first modulus, and having a second thickness smaller than the first thickness.
Legal claims defining the scope of protection, as filed with the USPTO.
4. The display device of claim 3, wherein the first adhesive layer comprises a concave portion overlapping the opening and recessed toward the display module.
5. The display device of claim 3, wherein the foam layer is disposed directly on the support film.
8. The display device of claim 1, wherein the first thickness is equal to or greater than about 80 μm and equal to or smaller than about 100 μm.
9. The display device of claim 1, wherein the second thickness is equal to or greater than about 3 μm and equal to or smaller than about 8 μm.
10. The display device of claim 1, wherein the core layer has a density equal to or greater than about 0.5 g/cm3 and equal to or smaller than about 0.8 g/cm3.
11. The display device of claim 1, wherein the second modulus of elasticity is equal to or greater than about 20 Mpa and equal to or smaller than about 24 Mpa at a temperature of about −20° C.
12. The display device of claim 1, wherein the foam layer has a modulus of elasticity that is equal to or greater than about 3 Mpa and equal to or smaller than about 5 Mpa at a temperature of about −20° C.
13. The display device of claim 1, wherein the core layer comprises a base resin comprising a plurality of pores defined therein.
17. The display device of claim 15, wherein the second modulus of elasticity is equal to or greater than about 20 Mpa and equal to or smaller than about 24 Mpa at a temperature of about −20° C.
18. The display device of claim 15, wherein the foam layer has a modulus of elasticity that is equal to or greater than about 3 Mpa and equal to or smaller than about 5 Mpa at a temperature of about −20° C.
